Patent JP-H11267817-A (JP)
Title: Press working
Inventor: ISHIKAWA SHUHEI
IPC: B22C9/06
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To make molten metal positively penetrate into fine gap portions inside the mold and into the interior of materials to be made composite, and to obtain a perfectly formed body without producing shrinkage cavity by forming the contact surface with the molten metal inside the mold with heat insulating material and pressing the mold metal in while keeping it hot. SOLUTION: A molten metal such as molten aluminum or molten copper is cast in from the feeder head 4 of a mold 1 whose contact surface with the molten metal is formed with a heat insulating material 6, and pressed with a punch 5, and then the molten metal, fills the internal space 2 of the mold while being kept hot, and completely penetrates into a fine gap portion 3. For this reason, the molten metal does not start solidifying before it reaches the end portion of the gap portion 3 as in the case of the conventional method, and a perfectly formed body is obtained. Further, it is preferable to form an air vent 8 penetrating through the mold wall and the heat insulating material 6, at a position away from the gate 7 of the mold 1. If such an air vent 8 is formed, no air is trapped in the end portion of the internal space 2 of the mold 1.

Title: Preparation of wholly aromatic liquid crystal polyester film
Inventor: MIYAMOTO TOMOHARU
IPC: B29C48/305
Filed: 1987-03-30
Abstract: PURPOSE:To orient highly a film in biaxial MD and TD and to attempt to improve the tearing and mechanical strength with a high tensile strength, by applying a specific magnetic field in the width direction of the film at the land part of a die when a molten resin is extruded from a flat die. CONSTITUTION:Melt extrusion is carried out while a magnetic field of 1,000-25,000 Oe is being applied in the width direction of a film, namely TD direction, during the passage of a molten resin through a die land, and while orientation of the molecular chains is thereby being generated in the magnetic field direction. In this case, as orientation in MD direction is also generated by shearing and tensile stresses applied at a lip of the die land in the extrusion direction of the resin, a film highly oriented in biaxial MD and TD can be prepared. When the value of the magnetic field is smaller than 1,000 Oe, orientation of molecular chains does not occur and, on the other hand, when the value is larger than 25,000 Oe, a limitation exists on the instrumental capacity; therefore it is not an industrially favorable means. A more favorable value of the magnetic field is 3,000-7,000 Oe.

Abstract: PURPOSE:To perform the transmission with high quality to a data video signal and to enable to decrease call loss to an audio signal, by transmitting a data video signal in time sharing multiplex system and in audio signal in frequency diffusion system. CONSTITUTION:A time sharing multiplexer 600 performs time sharing and multiplex for data and video signal in subscribers 650(1)-650(N) and transmits it to a  transmission line 608 via an LPF601. Further, SS modulators 602(1)-602(M) modulate the audio signal of the subscribers 651(1)-651(M) with the frequency diffusion (SS) system and transmit them to a transmission line 608 via a BPF603. Further, the output of the transmission line 608 passes through an LPF604 having the  same characteristic as the LPF601, and the time sharing multiplex signal component is converted into a video signal for subscribers 652(1)-652(N) via a time  sharing multiplexer 606. On the other hand, a part of the output of the transmission  line 608 is demodulated into an audio signal via a BPF having the same characteristic as the BPF603 and SS demodulators 607(1)-607(M). Thus, audio and data  video signals with different transmission quality can be multiplexed.

IPC: H05B33/10
Filed: 1990-03-22
Abstract: PURPOSE:To manufacture an EL luminous body having excellence in its manufacturing efficiency and also in the controllability of the arranged position of each of lead electrodes by forming the lead electrodes for both a back electrode and a transparent electrode respectively on the obverse and reverse of a substrate on the side of the back electrode. CONSTITUTION:An EL luminous body is manufactured in such a method that respective electrodes 2, 5 for both a back electrode 11 and a transparent electrode 81 are formed respectively on the obverse and reverse of a substrate 1 on the side of the back electrode. On this account, the next lead-electrode 5 can be bonded under the visibility of the preformed lead-electrode 2 and therefore the arranged position of each of the lead electrodes 2, 5 can be highly controlled to prevent inequality in a space between the electrodes 2, 5. Also the process of bonding the lead electrode 5 to a transparent electrode layer 81 formed of a damageable vapor deposition layer can be avoided, and therefore the purpose of obtaining a quality product can be accomplished through the process of bonding the lead electrode to a luminous layer 13 having excellence in shape-retaining strength. This can shorten the working hour for manufacture of the EL luminous-body so as to improve the manufacturing efficiency while preventing the generation of a product having poor electrification so as to also improve the yield rate of the EL luminous body.

Then, SiO2 29 of 1500Angstrom  is deposited on the substrate, and a main stripe window is formed by removing the SiO2 located at the upper part of an optional crystal grown part 30 in stripe form (width approx.=2mum) using a fluoric acid etchant. The laser chip shown in the diagram is formed by vapor-depositing an electrode metal (n-side: Av-Gu/Au, P-side: Cv/Au) on the processed wafer, and cut out after it has been alloyed. Through these procedures, the difficulties encountered in the technique used heretofore in crystal growth on the main stripe window are not observed at all now.

Title: Laser oscillation device
IPC: G02B27/28
Filed: 1992-03-30
Abstract: PURPOSE:To make an outer optical system simple in structure so as to enable a laser oscillation device to be lessened in cost and to be compact in structure as a whole. CONSTITUTION:Laser beams are reflected by a polarizing mirror 147 at an end 10A of a reflected-type resonator 10 to impinge on a polarizing mirror 146 located obliquely below the mirror 147, and laser beams are also reflected by a polarizing mirror 142 to impinge on a polarizing mirror 141 located obliquely above the mirror 142. That is, the polarizing mirror 141 and others are arranged so as to enable optical axes to cross each other. As the projected light beams are linearly polarized at an angle of 45 deg. with a horizontal plane as shown by an arrow 100, they can be circularly polarized by only a single 1/4-wavelength mirror. Therefore, an outer optical system can be made simple in structure. As optical axes are made to cross each other at a reflection side, a laser oscillation device of this design can be formed compact in structure.

Abstract: PURPOSE: To permit a driver to adopt a riding position which is maintainable for a long time, efficient, and easy by constituting the handlebar of a crosspiece with sideways portions connected to a bicycle steering post and extending from the bicycle steering post. CONSTITUTION: A handlebar 46 includes a crosspiece section 48, and a stem 34 is jointed at their central part by a stem clamp 50. The front handle portions 54 of the bars 46 are disposed so as to be apart a distance less than the width of the crosspiece section 48. By forming the portions 54 and the front loop portion 56, a rider is encouraged to adopt an easy riding position in which the frontal area is minimized. The portions 54 are disposed, when the rider R grips them, so as to be supported at a position where the rider's front arm F hangs over the section 48 by the bar 46. Therefore, front arm support mounts 74 are formed at the crosspiece of the bars 46, if necessary. The width W of the rider's silhouette is minimized by disposing the front arms or elbows so as to be relatively close together with each other, thus wind resistance is reduced.
